How to deploy node project to Heroku without verify

I'm new with heroku and keystoneJS. I made hello-world project and pushed the project to heroku git. I can't install add-on on heroku, because my account didn't verify. I don't want to verify my heroku account. I found the solution to deploy without verify from here So I created compose instance and set config vars on heroku. But when I run the app, I'm getting below error.
